Description
Pretreat Plus® Select
Antiscalant/Dispersant/Antifoulant
Antiscalant & antifoulants work differently but all with the same goal, keeping your RO/NF membranes running at maximum productivity. Antifoulants work to prevent organic and biological material, colloids, silt, and other fine particulates from attaching themselves to the membrane. Antiscalant temporarily keeps sparingly soluble salts in solution so they do not stick to the membrane and form scale. There are many different types of scale and foulants which can hinder membrane performance. Depending on your water chemistry, you may need a broad spectrum antiscalant, a specifically targeted antifoulant or a product which provides protection for both.
Pretreat Plus® Select is a classic antiscalant specifically formulated for feedwaters with lower levels of scale-forming minerals, such as seawater, to be cost effective. It is effective over a wide range of concentra-tions, and does not flocculate dissolved polymers such as residual coagulants or iron- or aluminum-rich silica. Use of this product is recommended for reducing the operating and capital costs of reverse osmosis (RO) and nanofiltration (NF) systems.
Features
- Controls inorganic scale over a large concentration range.
- Decreases precipitation of aluminum, iron, and heavy metal salts.
- Compatible with RO, NF, and UF membranes from all major manufacturers.
- Liquid formulation is convenient and easy to use.
- Certified under NSF/ANSI Standard 60 for drinking water production.
Applications
Classics: tried and true broad spectrum line of antiscalant fully capable for the majority of water applications.
